Dashcams (I call them “crash cams” because so many videos show drivers doing so many asinine things) can actually come in very handy by doing things like:
- Providing evidence in an accident.
- Recording risky drivers.
- Proving who robbed your car.
- Protecting you from insurance fraud.
What to buy
Low-end, single-channel (forward-facing) cams can cost as little as $50, with high-enders at around $400. Dual-channel (front- and rear-facing) cams go for $100-$400.
- At least 1080p resolution.
- Loop recording to erase old footage when the memory’s full.
- G-sensor: Triggered by impact, it keeps footage from being overwritten.
- Auto on/off.
- Date and time stamp (for court).
